How to read liver test report
The liver is an important metabolic organ in the human body, and its health directly affects overall physiological functions. Liver test sheets are an important tool for assessing liver health, but many people are confused by the various indicators on the test sheets. This article will explain in detail the key indicators of the liver test sheet to help you quickly understand the health of your liver.
1. Interpretation of core indicators of liver laboratory tests
| Indicator name | normal range | clinical significance |
|---|---|---|
| Alanine aminotransferase (ALT) | 7-40U/L | Elevated levels indicate liver cell damage (hepatitis, fatty liver, etc.) |
| Aspartate aminotransferase (AST) | 13-35U/L | Combined analysis with ALT can determine the degree of liver damage |
| Alkaline phosphatase (ALP) | 50-135 U/L | Elevated levels may indicate bile duct obstruction or bone disease |
| Gamma-glutamyl transferase (GGT) | 10-60 U/L | Sensitive indicators, often significantly elevated in alcoholic liver disease |
| Total bilirubin (TBIL) | 3.4-20.5 μmol/L | Reflects bile excretion function and is an important indicator of jaundice |
| Albumin (ALB) | 35-55g/L | Lower levels suggest chronic liver disease or malnutrition |
2. Common reasons for abnormal indicators
1.Elevated transaminases: Viral hepatitis (hepatitis B/C), alcoholic liver disease, drug-induced liver injury, non-alcoholic fatty liver disease, etc.
2.Abnormal bilirubin: Hemolytic diseases (indirect bilirubin elevation), bile duct stones/tumors (direct bilirubin elevation), hepatitis (both elevated).
3.decreased albumin: Late stage liver cirrhosis, nephrotic syndrome, long-term chronic wasting disease.
3. Key points of comprehensive analysis of test orders
| Indicator combination | possible disease | Recommended to check |
|---|---|---|
| ALT+AST is significantly elevated | acute hepatitis | Hepatitis virus screening |
| Elevated ALP+GGT | bile duct obstruction | Abdominal B-ultrasound/CT |
| Elevated TBIL + skin itching | cholestasis | Autoimmune liver disease antibody testing |
| ALB decrease + ascites | Cirrhosis | liver fibrosis scan |
4. Special precautions
1.fasting requirement: Liver function tests usually require fasting for 8-12 hours to avoid diet affecting the accuracy of the results.
2.drug effects: Antibiotics, lipid-lowering drugs, anti-tuberculosis drugs, etc. may cause an increase in transaminases. The doctor must be informed of the medication history before the examination.
3.dynamic observation: A single abnormality needs to be combined with clinical manifestations. It is recommended to reexamine after 2-4 weeks to observe the changing trend.
4.comprehensive assessment: A comprehensive judgment needs to be made in combination with imaging examinations such as ultrasound and CT, as well as auxiliary indicators such as platelets and coagulation function.
5. The latest hot topics in liver disease prevention and treatment (the entire network has paid attention to them in the past 10 days)
1.Research and development of new drugs for non-alcoholic fatty liver disease: Clinical research on GLP-1 receptor agonists in improving liver fibrosis has triggered heated discussions.
2.Artificial intelligence interprets test orders: Many hospitals have launched AI-assisted diagnosis systems that can automatically mark abnormal indicators and generate recommendations.
3.Liver cancer early screening technology: The sensitivity of liquid biopsy technology in detecting circulating tumor DNA (ctDNA) has been increased to over 85%.
4.Liver damage after COVID-19: Research shows that about 18% of recovered patients have persistent liver function abnormalities. It is recommended to recheck liver function 3 months after recovery.
By systematically understanding the interpretation methods of liver test sheets, you can more accurately grasp the health status of your liver. If abnormal indicators are found, please seek medical advice promptly for professional evaluation and do not self-medicate. Regular physical examination (liver function test once a year is recommended) is an effective means to prevent serious liver disease.
